Absolutely perfect
Color: Pink, Size: 23.8''D x 22.3''W*38.4''H
Love the color and it’s very comfortable. I can also use an additional back rest when needed. It’s small enough for my limited work space, but large enough to accommodate my height requirements. It was quite easy to assemble, as I frequently put furniture together. I’ve had it for about a month and I’m hoping that it lasts a good while.
